MACHINE FOR MOLDING CARWAXLE BOXES.

SPECIFICATON forming part of Letters Patent No. 681,785, dated September 3, 1901.

Application led April 13, 1901.

T all whom, t may concern,.-

Be it known that I, PHILIP T. IIANDIGEs,

a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Machines for Molding Car- AXle Boxes; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My present invention is designed more particularly to provideanovel machine for molding car-axle boxes, although it may be employed for other uses; but in the accompanying drawings and in the following description I have described and illustrated the same as especially adapted for molding car-axle boxes; but I would have it definitely understood that I do not limit myself to molding any particular article of manufacture.

My invention consists of the structure, combination, and arrangement of devices hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a View in perspective illustrating the body or inclosing case. Fig. 2 is a vertical cross-section through said box on the line 2 2, Fig. at, and through a car-aXle-box pattern and the flask, showing also portions of the interior construction within the body. In this View the pattern is shown in elevated position. Fig. 3 is a similar view in vertical cross-section through the body and flask, the pattern being shown withdrawn into the body or case of the machine. Fig. et is a View in longitudinal section showing parts in elevation. Fig. 5 is a plan view of the body.

Among the objects of my invention is to provide a low machine to facilitate the operation of the same; also, to provide a portable machine.

In carrying out my invention the supporting-body or inclosing case of the machine is indicated at a. Supported therewithin are fixed standards b o. These standards are supported in any suitable manner, as upon 5o bases c. Upon each of said standards is located a supporting-sleeve d, said sleeves to Serial No. 55,614. (No model.)

be engaged with a pattern e, su pported thereupon. I have shown two standards, each provided with a su pporting-sleeve d, engaged with the pattern; but I do not limit myself to any definite number of standards, as one or more may be employed within the scope of my invention. The sleeves d may be engaged with the patterns in any suitable way, as by bolts f. The shaft gis shown provided with 6o an operating handle or lever 7i, said shaft being connected with a system of levers or lazy-tongs (indicated at t) to simultaneously operate said series of tongs if plural tongs are used. To this end the shaft may be provided with crank arms j, connected with said lazy-ton gs. The lazy-tongs are connected at their upper ends with their respective sleeves d and at their lower ends maybe engaged with the corresponding bases c. A 7o flask is indicated at 7a, into which the pattern is elevated and from which it is withdrawn by means of the lazy-tongs engaged with the shaft g. The body a is also provided with a top or cover l and also with trucks or wheels m, whereupon the machine may readily be transported from one place to another. The base of the pattern is provided with an oritice, as at fa, through which the corresponding standard b may enter the pattern when 8o the pattern is depressed or withdrawn into the body or inclosing ease a and out of the flask. A lateral expansion of the pattern is indicated at r. The lazy-tongs are located beneath the patterns and when the pattern is depressed are folded compactly therebeneath. The crank-shaft is located to one side of the body and toward the base thereof, the crank-arms projecting underneath the pattern. 9o

It will be obvious that I take advantage of the space in the pattern to permit the sliding of the pattern down over the standards, so that I am thus enabled to get a low machine. One great trouble with machines of this class heretofore devised is their inconvenient height; but by utilizing the space within the pattern thus and by the folding movement of the lazy-tongs I am enabled to construct my machine in very close compass. tongs obviously will fold up compactly, so that I need to have the body of the machine The lazyroo only of sufficient height to receive the folded lazy-tongs, together with the height ofthe pattern when slid down over the standards. By withdrawing the pattern into the boX and over the standards and by employing the lazytongs I get a machine easily worked in packing the sand in the l'lask about the pattern.

In operation the machine is placed at one end of a long row of molding-sand prepared for molding, and as the molds are made they are placed before the machine and the machine drawn back to the place that was occupied by the sand used up in making the molds, thereby making it unnecessary to carry the sand to the machine or to carry the molds away from the machine. It the machine were stationary, it would be obviously necessary to carry the sand to the machine; but by my construction I am enabled to roll the machine along to follow up the said row as the sand is worked up into molds. Moreover, bythe mechanism which I have employed a very short stroke of the lever or handle h will actuate the pattern either to lift it up into the ilask or to withdrawit into the body or case of the machine. To lock the pattern in its position within the flask, any suitable means may be employed-as, for instance, a couple of stops, (indicated at q q.) The working parts of the machine are contained inside the supporting body or ease.

What I claim as my invention isl. In a molding-machine, the combination with a movable supporting-body, of a fixed standard carried by said body, a pattern reciprocatory upon said standard, a crank-shaft provided with a crank-arm journaled in said body toward the base thereof and at one side the longitudinal center ofthe body, and lazytongs connected with'said crank-arm and with said pattern to raise and lower the pattern, said lazy-tongs when the pattern is in depressed position folded beneath said pattern.

2. In a molding-machine, the combination with a supporting-body, of a stationary standard carried by said body, a supporting-sleeve reciprocatory upon said standard, a pattern engaged with the sleeve also reciprocatory upon said standard, a shaft provided with a crank-arm journaled in said body toward the base thereof and at one side the longitudinal center of the body, and lazy-tongs located below said pattern connected with said crankarm and with said sleeve to raise and lower the pattern, said crank-arm extending underneath the pattern, and the lazy-tongs when the pattern is in depressed position folded underneath said pattern.

3. In a molding-machine, the combination with a supporting-body, of plural standards carried by said body, a pattern reciprocatory upon said standards, plural lazy-tongs connected with said pattern, and a crank-shaft journaled in said body connected with said lazy-tongs, said lazy-tongs when the pattern is in depressed position folded underneath said pattern.

In testimony whereof I sign this specification in the presence of two witnesses.
